someone camped across the great wall of china in 15 months. i get this from thegreatwalk.com
Considering that the entire Great Wall (i.e. several sections and branches of walls and natural formation) is said to be 8852 km (5500 mi), and an average walk is 5 km/h (3 mi/h). If you are dedicated and walk 12 hours per day, (with a crew carrying food, clothes, and a portable shower), it's going to take 148 days or approximately 5 months.
All by yourself it's likely to take twice that time. The good news is you can eat for $2 per day and less than 10% is visited (meaning who cares if you smell).
